28. NORTH QUEEN ALIA AIRPORT TREATMENT PLANT 1. Long term development in South Amman Area According to the Consultants Study Report the long-term strategy for the South Amman Area foresees two independent sewerage schemes and two wastewater treatment plants:

• North Queen Alia Airport Treatment Plant (eastern drainage area) This treatment plant will receive the wastewater of the eastern drainage area.

• Al Jeeza Treatment Plant (western drainage area)

This treatment plant will receive the wastewater of the western drainage area. Details of proposed Al Jeeza system are given under Section 20. 2. Proposed North Queen Alia Airport Treatment Plant Figure 28.1 shows the layout of the proposed sewerage system, which will be implemented in 3 Phases. The project foresees the construction of the North Queen Alia Airport Treatment Plant designed for the wastewater production in 2020. It will be based on an extended aeration process including maturation ponds for tertiary treatment. Produced sludge will be treated by sludge holding tanks and drying beds. Figure 28.2 shows the proposed treatment system. The projection of the wastewater production is shown in the following table (acc. to Consultant’s Study Report). The plant will be implemented in two phases, whereby the final capacity will be reached

in 2020: 28,500 m³/d (283,000 connected inhabitants) The effluents could supply irrigation water for an area of about 460 ha in 2020 taking into account the demand for alfalfa, barley and sudan grass as summer crops and barley and ryegrass as winter crop (see following table). Suitable land for irrigation was identified northwest of the treatment plant. A 1.5 km long transmission main to areas will be constructed to discharge treated effluent by gravity to the land. Proposed wastewater reuse areas are presented in the Figure 28.3. The investment costs (Phase 1, 2 and 3) excluding engineering and contingencies (based on 1994 prices) are:

Treatment plant 8.44 million JD Local sewerage 22.46 million JD Collector sewerage 5.71 million JD Trunk sewerage 4.78 million JD Irrigation facilities 2.83 million JD Total capital costs 44.22 million JD


SA3-305

Investment costs subdivided in Phases 1 (2002/11), 2 (2012/20) and 3 (2021/26) are as follows: (price basis 2000, in mio. JD)

29. NORTH JORDAN VALLEY TREATMENT PLANT The proposed North Jordan Valley Scheme (Shuna North Scheme) area is located in the northern part of Jordan Valley extending from Adasiyyah in the north to Sleikhat in the south. Presently, there exists no sewerage system. The following communities will be connected to the proposed scheme:

Phase 1 (2001/03): North Shuna, Sheikh Hussein, Zemalia, Tabquat Fahl, Masharie, Wadi El Yabis

Phase 2 (2008/10): Manshiya, Waqqas, Merrazeh, Abu Habeil, El Qarn Phase 3 (2018/20): Adasiya, Sakneh, Fadin, Sleikhat

Figure 29.1 shows the layout of the proposed sewerage system (Study Report of Metcalf & Eddy). Without any alternative project proposals and studies the design considers an almost 40 km long main collector with 9 pump stations in the final phase. This long trunk main will lead to enormous odor (among other) problems, because the flow time will be up to one day and the long term average monthly temperatures are rather high (between 14 and 30 °C). The project foresees the construction of the North Jordan Valley Treatment Plant designed for the wastewater production in 2020. It will be based on an extended aeration process (modified Ludzak-Ettinger process) including nitrogen removal. Rapid sand filtration is proposed as tertiary treatment. Produced sludge will be treated by gravity thickeners and drying beds. Figure 29.2 shows the proposed treatment system. The projection of the wastewater production is shown in the following table (acc. to Consultant’s Study Report). The projection of collected wastewater considers continuously 24 l/c/d for infiltration/inflow allowance, which seems unrealistic because the groundwater table is generally 10 m below ground level. The plant will be implemented in two phases, whereby the final capacity will be reached

in 2025: 10,700 m³/d (112,000 connected inhabitants) and in 2015: 7,700 m³/d (86,000 connected inhabitants)

The effluents could supply irrigation water for an area of about 500 ha in 2020 taking into account the demand for mixed crop pattern (see following table). Irrigable land is available south and west of the site. Treated effluent will be pumped to a elevated reservoir and from there discharged by gravity (1.1 km long pipeline) to the proposed land. Proposed wastewater reuse areas are presented in the Figure 29.3. The investment costs based on 1999 prices are (Phase 1 measures only):

Treatment plant (primary and secondary treatment) 10.36 million JD Networks 12.72 million JD Reuse system 0.78 million JD


SA3-312

Misc. equipment 0.75 million JD Total base costs 24.61 million JD Physical contingencies 3.69 million JD Engineering 2.92 million JD Total investment costs 31.21 million JD

According to the Consultant’s Study Report implementation of proposed construction measures is foreseen during the years 2001 to 2003 (Phase I).

30. SHUNA SOUTH TREATMENT PLANT The proposed Shuna South Scheme area is located in the south of Jordan Valley extending from Karamah in the north to Al Jeld in the south. Presently, there exists no sewerage system. The following communities will be connected to the proposed scheme: Karameh Rawdhah, Jofet Al Kafrein, Sakanat Ashoeneh, South Shuna, Ramah, Kafreen Al Jeld and Hamred&Jarga. Figure 30.1 shows the layout of the proposed sewerage system. The project foresees the construction of the Shuna South Treatment Plant designed for the wastewater production in 2020. It will be based on an extended aeration process including slow sand filtration as tertiary treatment. Produced sludge will be treated by gravity thickeners and drying beds. Figure 30.2 shows the proposed treatment system. The projection of the wastewater production is shown in the following table (acc. to Consultant’s Study Report). The plant will be implemented in two phases, whereby the final capacity will be reached

in 2020: 6,500 m³/d (58,900 connected inhabitants) The effluents could supply irrigation water for an area of about 100 ha in 2020 taking into account the demand for alfalfa and sudan grass (see following table). Downstream of the treatment plant is no land suitable for irrigation. Irrigable land is available north and west of the site. A pump station together with a 3 km long rising main will be constructed to discharge treated effluent to the land. Proposed wastewater reuse areas are presented in the Figure 30.3. The investment costs based on 1998 prices are:

Treatment plant (primary and secondary treatment) 4.92 million JD Networks 13.79 million JD Tertiary treatment and pump station (reuse system) 1.72 million JD Total base costs 20.42 million JD Physical contingencies 2.04 million JD Engineering 2.25 million JD Total investment costs 24.71 million JD

According to the Consultant’s Study Report implementation of proposed construction measures is foreseen during the years 2001 to 2003 (Phase I).

31. TORRA TREATMENT PLANT The proposed Torra Scheme area is located some 15 km northeast of Irbid extending from Torra in the southeast to Donaya in the northwest. Presently, there exists no sewerage system. The following communities will be connected to the proposed scheme: Torra, Shjara, Amrawa and Donaya. Figure 31.1 shows the layout of the proposed sewerage system. The project foresees the construction of the Torra Treatment Plant designed for the wastewater production in 2020. It will be based on an extended aeration process including slow sand filtration as tertiary treatment. Figure 31.2 shows the proposed treatment system. Produced sludge will be treated by gravity thickeners and drying beds. The projection of the wastewater production is shown in the following table (acc. to Consultant’s Study Report). The plant will be implemented in 2010, whereby the design capacity will correspond to the wastewater production

in 2020: 5,600 m³/d (48,100 connected inhabitants) The effluents could supply irrigation water for an area of about 90 ha in 2020 taking into account the demand alfalfa and sudan grass (see following table). As the treatment plant is located at the edge of the wadi it will be about 1km to a suitable elevation to allow distribution by gravity for irrigation. A pump station together with a 1 km long rising main will be constructed to discharge treated effluent to the land. Proposed wastewater reuse areas are presented in the Figure 31.3. The investment costs based on 1998 prices are:

Treatment plant (primary and secondary treatment) 4.47 million JD Networks 8.44 million JD Tertiary treatment and pump station (reuse system) 0.99 million JD Dam/storage (pond for reuse) 1.86 million JD Total base costs 15.76 million JD Physical contingencies 1.58 million JD Engineering 1.73 million JD Total investment costs 19.07 million JD

According to the Consultant’s Study Report implementation of proposed construction measures is foreseen during the years 2010 to 2012.

33. WADI SHALLALA TREATMENT PLANT Wadi Shallala Treatment Plant is part of the sewerage system considered by the long-term development in Greater Irbid Area (compare description of the Treatment Plant Irbid Central under No. 6). The Wadi Shallala drainage area is part of the Yarmouk catchment area. The confluence of Wadi Shallala and the Yarmouk River are upstream of the planned Wahdah Dam, which is proposed to serve as a reservoir for water supply. Therefore, any discharge of untreated sewage into Wadi Shallala could cause severe health risks in the future. In the sewerage sector, all infrastructure works have to be newly constructed including the collection system, the interceptors and the wastewater treatment to protect the water sources and to enable its reuse for the irrigation of crops, etc.. The interceptors SH to SH3 will be constructed with pipes of diameter DN 300 to DN 900 with a total length of 47 km. The sewer network for the following communities (see Figure 33.1) will be constructed from concrete pipes of diameter DN 200 to DN 400.

Irbid South- East 46 km Aydun 54 km Al Husn 69 km As Sarih 69 km Bushra 35 km Huwwara 59 km Mukh. Al Husn 45 km Sal 32 km

The connection of Al Hasan Industrial Estate to the Wadi Shallala Plant cannot be recommended due to economic reasons. The proposed project foresees the construction of the Wadi Shallala Treatment Plant designed for the capacity in 2015 with extension up to 2025. It will be based on extended aeration process including nutrient removal (nitrification, denitrification) and sand filtration. Figure 33.2 shows the proposed treatment system. The projection of the wastewater production is shown in the following table (acc. to Consultant’s Study Report). The capacity of the plant will be

In 2015: 15,000 m³/d (172,000 inhabitants) In 2025: 22,000 m³/d (240,000 inhabitants)

The proposed reuse facilities should be developed east of Sal. Reuse at the Yarmouk University of Science and Technology and in the Jordan Valley would be less economical and less environmentally sound. According to the Consultant’s proposal the treated wastewater will be pumped through a pipeline 2,300 m long to the reuse area east of Sal. A storage pond/dam will provide storage facilities for 2 or 20 days retention time. A concrete reservoir (14,000 m³) shall be


SA3-331

constructed at the highest Section of the irrigation area, as well as a service main 6 km long. Proposed wastewater reuse areas are presented in the Figure 33.3. The reuse of treated wastewater for irrigation purposes implicates the construction of:

• a storage pond or dam (30,000 m³ storage capacity) for the treated wastewater (considered in the costs WWTP).

• two pumping stations • a double pipeline DN 600 with a length of about 2,300 m • a concrete reservoir with a storage capacity of 8,000 m³

The effluents could supply irrigation water for an area of about 360 ha in 2020 taking into account the demand for sudan grass as summer crop and barley and ryegrass as winter crop (see following table). The investment costs based on 1998 prices are:

Treatment Plant Wadi Shallala 15.97 million JD Interceptor, trunk sewers 5.23 million JD Network and house connections 17.09 million JD Reuse system 5.59 million JD Vehicles 0.68 million JD Engineering 5.10 million JD

Total Base Costs 49.66 million JD Physical Contingencies 4.96 million JD Financial Contingencies 2.71 million JD

Total Investment Costs 57.33 million JD

According to the Consultant’s Study Report implementation of proposed construction measures were foreseen until end of 2002. However, this implementation schedule is not anymore valid. It is more realistic that the measures will be completed end of 2004. In July 2000 the Ministry of Water and Irrigation prepared Terms of Reference for a study for reuse of treated wastewater for the Greater Irbid Area. It is proposed that the German Development Bank (Kreditanstalt fuer Wiederaufbau, KfW) will finance this study.
